  • Patent number: 10158256
    Abstract: A contactless connector apparatus is provided with a first coil closely opposed to a second coil so as to be electromagnetically coupled thereto. The first coil includes: an inner transmitter coil wound around an axis passing through its center; and an outer transmitter coil wound around the axis and outside the inner coil. One end of the outer transmitter coil is connected to one end of the inner transmitter coil such that, when a current flows through the transmitter coils, a direction of a loop current generated around the axis by a current flowing through the inner transmitter coil is opposite to that of a loop current generated around the axis by a current flowing through the outer transmitter coil. A self-inductance of the outer transmitter coil is larger than that of the inner transmitter coil.

  • Patent number: 9035605
    Abstract: This non-contact charging module can be suitably used by suppressing a change of an L value of a coil that is provided in the non-contact charging module, and achieves size reduction, even in the cases where a magnet that is provided in the other non-contact charging module is used or not used. The module is characterized in that: the module is provided with a primary side coil (21a) wherein a conducting line is wound in a substantially rectangular shape, and a magnetic sheet (51) that is provided with a surface on which the primary side coil (21a) is placed; and that a substantially rectangular-shaped hollow portion of the primary side coil (21a) has the short side thereof shorter than the diameter of a circular magnet (30a), and the long side thereof longer than the diameter of the circular magnet (30a).
